Answer:
this is the full solution of your question
y = total snow accumulated
x = hours
the ground has 0.2 inches of snow before the data starts
y = 1.5x+0.2
0 hours = x = 0, so y = 0.2 inches
after 9 hours, we predict that 13.7 inches of snow will have accumulated
y = 1.5(9)+0.2 = 13.7
An=A1+(n-1)d
-20=A1+(15-1)x-7
-20=A1+14 x -7
-20=A1-98
+98 +98
-98+98=0
-20+98=78
A1=78
The numbers of pears and apples bought are 16 and 20 respectively
let
x = number of pears
y = number of apples
He bought 4 more apples than pears. Therefore,
He bought a number of pears and apples and paid $128 for them. Therefore,
<h3>System of equation:</h3>
y - x = 4
4y + 3x = 128
Therefore,
3y - 3x = 12
4y + 3x = 128
7y = 140
y = 140 / 7
y = 20
Therefore,
20 = x + 4
x = 20 - 4
x = 16
